Intex zipper is horrible.!
Taking about sound quality. it's pretty good
Bass is good too
BUT it really doesn't matter. Because Zipp affect the wire.
I Buyed. And it not even stayed for one month.
I exchanged with intex service center.
Again it got that same problem. VERY disappointed.
The idea is excellent. But the really doesn't work.
DON'T BUY.
